呃，Jenny和Jelly都挺好的。Jenny比较大众；Jelly--想到果冻的同时我就想到jellyfish(水母）-.-。如果你要别致点另类些的英文名，和你名字音相似的有：
Jaylee, as a girl's name is a variant of Jae (American).
这个名字没有特殊的含义，jay+lee的合体。非要解释的话，我复制了一段---
Jay as a girl's name (also used as boy's name Jay), is of Latin origin, and the meaning of Jay is "blue crested bird". Also a medieval name possibly from Gaius (Latin) "happy"; also pet form of names beginning with J- (see also Dee and Kay). In Hindi, it is derived from Sanskrit, meaning "victory". The name has been inspired by John Jay, a great American jurist. The name is also used in combination with other names. Gymnast Jaycie Phelps.Jay has 13 variant forms: Jae, Jalin, Jaline, Jaya, Jaycie, Jaye, Jayla, Jaylah, Jaylan,Jaylene, Jeh, Jey and Jeyla.
Jay is a somewhat popular first name for women (#2126 out of 4276) (1990 U.S. Census)
大概说下意思以防万一：
Jay可作男女名，源自拉丁语，意思是蓝色羽冠的鸟（不知道和blue jay或blue bird有无关系，有兴趣自己查一下）；中世纪拉丁语Gaius的变体，意思是“快乐、幸福（的)"；所有以字母J开头的英文名的爱称/昵称；在印地语中，Jay源自梵语，意为”胜利“。Jaylee这个名字的灵感来自于美国著名的法理学家Gymnast Jay。Jay也常和其他名字合用，如Gymnast Jaycie Phelps. Jaycie可译作洁西或杰西-.-
Jay的十三种变体：Jae, Jalin, Jaline, Jaya, Jaycie, Jaye, Jayla, Jaylah, Jaylan,Jaylene, Jeh, Jey and Jeyla.
1990年的美国人口普查结果显示，4276个女性中叫Jay的就有2126个-.-
为了说明这个名字并不是我捏造出来的，你可以参考一下给女儿取名为Jaylee的美国父母的说法：
Kelly Jevnager Weiss · Blaine, Minnesota
My daughter is named Jaylee I love it and so does she. Her name comes from my mom Janet lee. She will be 8 in march and we have never come across another Jaylee.
明尼苏达州的Kelly Jevnager Weiss·Blaine说，我的女儿取名为Jaylee，我和她都非常喜欢这个名字。这个名字的灵感来源于我母亲的姓名--Janet Lee。3月份我的女儿就8岁了，到现在我们都没碰到一个同名的。（不像中国啊，各种婷，丽-.-)
Amy Phillips
When I was pregnant I was looking for a unique name. I combined my husband and Father in law's name and came up with Jayleigh. Her middle name is equally original. She is now 8 and we couldn't imagine her with any other name!
Amy Phillips说，我怀孕期间一直想找一个独特的名字，结合我丈夫和岳父的名字我得出了Jayleigh这名儿。她的中间名同样很独特。Jayleigh现在已经8岁了；我们完全无法想象她叫别的名字~
Ashley Babey · Regina, Saskatchewan
I had never heard of this name but when my husband and I found out we were expecting a baby we decided to combine our names (Jason&Ashley) and we got Jaylee.
来自加拿大萨斯喀彻温省的Ashley Babey·Regina说，我之前从没听过这个名字，但在丈夫和我发现我怀孕之后我们决定结合我俩的名字--Jason和Ashley来给孩子命名，我们就得出了Jaylee这名儿。

名字的特殊含义通常是父母赋予的，并不一定有特定的解释。和你的中文名音相近这个解释就足够强大了。我赶脚Jaylee或Jalea都可以，挺好听的，比较独特。
再总之，看你喜欢了，你参考参考哈：）来自：求助得到的回答
